Application filed February 9, 1914. Serial No. 817,697.

To all whom t may concern:

Beit known that I, GEORGE B. KOHLER, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in VCar-VVindows, of which the following is a specification.

The object of my invention is to provide a car window sash with a Ventilating supplemental sash which forms part of the upper sash so that it can be opened to provide ventilation at the side of a car.

The invention also relates to certain improvements in the detail construction of the means for hinging the upper sash to the lower sash and the supplemental sash to the lower sash. Y

The invention also relates to the means for retaining the supplemental sash in posi- `tion in the 'upper sash and also to providing lmeans for deiiecting the air asl it passes through the ventilating opening.

In the accompanying drawings: Figure l is a transverse sectional vview of a portion of a car frame at the window opening, showing the sash inthe closed position; Fig. 2 is a detached perspective view showing the upper sash and a portion of the lower sash with the supplemental sash closed; Fig. 3 is a vertical sectional view through the upper sash and the supplemental sash; Fig. 4 is-a vertical sectional view showing the supplemental sash in the open position; Fig. 5 is an enlarged sectional view, showing theA latch for retaining the supplemental sash in the closed position; Fig. 6 is a vertical sectional view of the hinged jointfof the sash; Fig. 7 is a sectional view on the line a-a, Fig. 6; Fig. 8 is a detached perspective view of the hinge plate and the pivot for the supplemental sash; Fig. 9 is a view of the hinge plate for the upper sash; Fig. 10 is al detached perspective view of the upper portion of the lower sash at the hinge; Fig. 11 is a detached perspective view of the latch for retaining the supplemental sash to the upper sash; Fig. l2 is a detached perspective view of the pivoted stop to limit the movement of the supplemental sash; Figs. 13 and 14 are sectional views on the line ZJ? Fig. 2, showing the supplemental sash closed and open and the stop for limiting the movement; Fig. l5 is a sectional plan view on the lineo o, Fig. 5, showing the latch; and Fig. 16 is a detached perspective view of the deecton In the present instance, l is the side frame of a car.

2 is the roof structure of the ordinary type.

3 is the roof panel.

4 is the guide rail for the sash when it is raised.

5 is a guard rail Vfor preventing the supplemental sash from swinging in the event of being raised without being fastened.

6 is the lower sash of the ordinary con struction and 7 is the uppersash. These two sashes are connectedby a rib and recess joint, the rib 8 being on the lower sash and the recess 9 being on the upper sash, as clearly illustrated in Fig. 3. The two sashes are of metal, in the present instance, filled with wood, or other suitable material, but the sash may be made entirely of metal if desired. A sash of this type does not allow for ventilation at the upper part. The usual practice is to raise the entire sash and to allow the air to enter through the lower portion of the window, which is objectionable. ventilators in the roof of cars of this construction are provided, but in many cases it is desirable toprovide means for opening the sash at or near its upper end and this is accomplished by providing a supplemental sash l0, which is mounted in the upper sash, in the present instance, and is arranged to swing on the same pivot so that, when it is necessary, the supplemental sash can be swung into the car, asillustrated by dotted lines Fig. l. This aii'ords the necessary ventilation at the side of the car nea-r the top.

. The hinge for the sash is clearly illustrated in Figs. 6 to 10 inclusive, and consists of a combined hinge for the upper sash 7 and the supplemental sash 10. The upper sash 7 has a frame having a cross piece 1l and two side members l2. These side members extend to and are shaped to iit the round upper edge 8 of the lower sash 6. rIhe supplemental sash is quadrangular in shape and has a recess 9 for the rib 8 of the lower sash and snugly lits between the side members and the cross member 1l of the upper sash. Secured to each lower corner of the supplemental sash is a hinge plate 13, made as clearly shown'in Fig. 8, having a right angled section le carrying the pivot l5. This pivot extends through the opening in the plate 16 secured to the sidemembers 12 and into the opening 1'? in the side of the upper corner of the lower sash 6. The plate 16 is offset to accommodatethe portion 14 of the plate 13 and each upper corner of the lower sash is notched to receive both plates so that they will be Hush, as illustrated in Fig. 6, to allow the two sashes to travel in the guideways. By using a single pivot for rthe upper and the supplemental sash, the

thickness of the sash is not increased, nor is the meeting rail increased in width.

In order to adjust the supplemental sash 10, when in the `open position, I provide a stop 18, Figs. 12, 13 and 111, vwhich is pivoted to the said sash 10 and engages the side members 12, they being cut away to allow for the movement of the stop. ,The stop is controlled by a spring and has two notches so that it can engage the edge of the cut in the member 12 and hold the supplemental sash in either of two positions. To hold the supplemental sash in the .closed position, l may usethe latch illustrated in Figs. 2, 5, i1 and i5.

2O 1s a platerecessed at 2,1, for the latch bolt 22 having a beveled edge so that it can be forced past the keeper 2? on the upper sash 7, Fig. 2. Y

211 is a rod bent to form an arrn 25, which enters a recess 26 in the bolt I2,2 Aso that when thel rod is turned the bolt can be raised and lowered, Secured to the rod is a flat arm v27 which rests in the recess 28 in the upper sash and on the rod is a coiled spring 29 which tends to raise the bolt 22 so that when the supplemental sash is closed the bolt rests back of the keeper' 28. The plate 20 and its latch mechanism .is mounted in a recess in the upper end of the supplemental sash andis inclosedby the metal frame of the sash. The metal fra-me has an opening for the bolt and for the operating arm 27. Y

In order to direct air through the opening and into the car, l provide a deiiector 30, which is pivoted at 31 to the `car frame and rests on the upper edge of Vthe upper sash when the sash is closed. The deiectonis cut awa.` to clear the lip 32 of the guide. This deiiector prevents the air from passing Copies of this patent may be obtainedl for iive cents each, by addressing thek Washington, I).

lVhile I prefer to mount the supplemental sash on the same pivotV as the upper sash,

this construction may be modified without departing from the essential features of the invention.
